IMHO this is a bad setup. Because you are reading and writing to
multiple disks at at time, you may have some speed-up, but you only
get half the total space. And you are vulnerable to some two-disk
failures. If you went to RAID-6, you'd get the same basic performance
and space
but would be immune to two-disk failures.
But RAID-5 and RAID-6 require more computational power.
RAID6 has to generate 2 parities.
Largely irrelevant. The computational power in creating RAID 6 parity
bits is minuscule for today's processors.
